Questions
Statement 1: If the frequency of alternating current in an AC circuit consisting of an inductance coil is increased, then current gets decreased.
Statement 2: The current is inversely proportional to frequency of alternating current.
detailed solution
Correct option is A
When frequency of an alternating current is increased, the effective resistance of the inductive coil increases. current XL=ωL=2πfL in the circuit containing inductor is given by I=VXL=V2πfL. As inductive resistance of the inductor increases, current in the circuit decreases.Talk to our academic expert!
